Journal ArticleDOI
RNA polymerase-dependent mechanism for the stepwise T7 phage DNA transport from the virion into E. coli
Sergei K. Zavriev,M.F. Shemyakin +1 more
TL;DR: It would appear that some class I and (or) II gene product(s) are obligatory components of the final stage of 17 DNA transport, which is tightly coupled with its transcription and that a mechanical function is carried out by RNA polymerase.
Journal ArticleDOI
Circular dichroism anisotropy of DNA with different modifications at N7 of guanine
Sergei K. Zavriev,L. E. Minchenkova,Michaela Vorlíčková,A.M. Kolchinsky,M.V. Volkenstein,V. I. Ivanov +5 more
TL;DR: It was shown that in most cases, except that of the protonated DNA, the degree of orientation was only slightly less than that for pure DNA, and this demonstrated the absence of aggregation and of appreciable denaturation.
Journal ArticleDOI
On the flexibility of the boundaries between the A′-form and B′-form sections in DNA molecule
TL;DR: The degree of orientation of DNA in a flow has been studied within the interval of the B - A transition induced by ethanol and shows that the flexibility of a boundary is small, so that several dozen of boundaries are required to simulate free rotation.
Journal ArticleDOI
Conformational possibilities of double-helical nucleic acids: Theory and experiment
V. I. Ivanov,Victor B. Zhurkin,Sergei K. Zavriev,Yu. P. Lysov,L. E. Minchenkova,E. E. Minyat,Maxim D. Frank-Kamenetskii,A. K. Schyolkina +7 more
TL;DR: In this article, the authors present a survey of the properties of the B-A transition of DNA in solution: the degree of cooperativity and influence of sequence, and its possible role in genes activation.
Journal ArticleDOI
Novel Thionins from Black Seed (Nigella sativa L.) Demonstrate Antimicrobial Activity
Alexey S. Vasilchenko,A. N. Smirnov,Sergei K. Zavriev,Eugene V. Grishin,Anastasia V. Vasilchenko,Eugene A. Rogozhin +5 more
TL;DR: Data indicate that black seed thionins are biologically active molecules that may be considered to be perspective antibacterial agents, such as bactericidal and fungicidal effects.
